Another possibility, depending on how long ranged the future "spider detector" is could be to accelerate beyond that range and then coast in ballistically until you reach your launch point (or possibly until you slide through the sensor shell of the enemy and any spider usage would get lost in the in-system traffic 'noise'.MAD-4A wrote:The vulnerability of the spider ships combined with their reliance on stealth and lack of accel (translate to blue water “speed”) makes them the “U-boats” of the Honorverse. As the sub showed, no amount of stealth can keep you invisible forever. Even if the stealth paint absorbed everything, that in itself can be used against it. If you know there’s one out there (previous attack for example), you can launch a spread of contact nukes beyond its estimated location and watch for “holes” in the EM return from the explosions. Then target the “holes”. Eventually tech would be developed to detect the ships (either threw breaking the stealth or detecting the spider drive itself) from what I’m seeing (& let me know if you have other info I don’t), the “spider drive” seams to use the same tech as a normal wedge drive but instead of concentrating gravity into a huge massive field to force the ship forward with difference in potential, it uses small amounts of gravity locally to pull the ship forward (like the S.W. Yuuzhan Vong’s Dovin Basal) It “grabs” a “patch” of space and “pulls” the ship toward it like a rope climber's arms climbing a rope. If this is true then they can be detected with gravitics if you know what to look for (like a sonar tech having to know what sound to listen for). They can however be easily “washed out” by the heavy use of wedges & sidewalls in close vicinity, (perhaps using a “neutral” civilian ship at slow accel to approach a target area while several spider ships fallow along close into its wedge signature).
Also, for detection we've speculated that the "grab" on the Alpha wall might distort (or in best case even partially reflect) other ripples along the wall. That could let the FTL comm tech potentially serve as a basis for an active sonar analog. (With the usual downside of active sonar - that the platform emitting it is obvious as hell and from beyond the range that the sonar can detect the target)
